SPECIFICATION forming part of Letters Patent No. 396,825, dated January 29, 1889. Application filed July 19, 1887. Renewed August 3, 1888. Serial No. 281,873- (No model.)

To all 111710711 it may eon-c0772.-

Be it known that I, GARRETT \Y. LOW, a citizen of the United States, residing at Kalamazoo, county of .I\'alamazoo, State of Michi gan, have invented a new and useful Tree- Feller, of which the following is a specification.

This invention has for its object the constrnction of a machine for telling trees, substantiall y as l elow described and claimed.

In the drawings forming a part of this specification, Figure 1 .is a plan view of the machine with the tree in cros section; llig. 2, a perspective view of a lettered detail. in Fig. 1; l ig. -3, a section on line 2 2 in Fig. 1; and Fig. 4c shows lettered details from Fig. 1 showing a change below described.

Referringto the lettered parts of the drawings, A is a lever, to which a horse or other power may be applied to sweep the same around the tree I.

An arm, D, is pivotally attached to the end E of the lever A, and. to the other end of said arm is rigidly attached the cutting-tool L. This tool. is preferably like a gage at the cutting end, Fig. 2, but may be ot any shape which will cause it to out and remove from the tree a shaving, thus forming a groove into and around the tree P, Fig. 1.

At F is shown a gage attached to the arm I) just forward of the cutter L to control the depth of cut. In Fig. 1 the end of the gage next to the tree is blunt and does not extend quite so far in as the cutter L. In Fig. 1L the end of the gage I is sharp and cuts a line forward of the eutting'tool L, and the sharp ends of both are on about the same plane. Either style of gage is operative; but that in. Fig. 4 is deemed preferable, for the reason that it assists in holding up the machine, especially when starting, and it allows the shaving to yield from the cutting-tool more readily.

X is a brace to the gage F.

At (Z is shown a brace passed through the lever A and attached to the arm I) at one end. The other end extends through and beyond the lever, and is provided. with a spring, 1', held and governed by a hand-wheel.

By this means the cutting-tool operates under a spring resistance and automatically conforms to irregularities in the shape of the tree, and. is also caused to follow deeper into the tree as the grooving process continues.

The dotted position of the arm D, Fig. l, and the cutting-tool is designed to show the operation mnchuled, at which time the machine is removed to anothertreeand. the central pmtion yet uncut. is severed. by hand with a saw. This is to guard against the falling tree breaking the machine. However, the machine can be adjusted to entirely sever the tree, it desired.

The lever A is provided with adjustable guides n and ll, the latter of which yields against the resistance of the spring S on the rod 1'. These guides are pivoted to the lever A, and the position of the guide 0 a may be changed by hand-screw u, it desired. These guides assist in hohling up the machine. The ends which en gage the tree may be sharpened, or they may be provided with the wheels a i), said wheels being sharp, or at least thin, at the edge, so as to enter the bark when the operation commences and to follow the groove during the operation. A less number of guides or a greater ni'nnbm: maybe en'lploycd, as the need demands. lloth ot the springs S and r may be made stilt'er or weaker by turning the hand-wheels which retain them in place.

A wheel, 0, may be employed to follow the groove, but not necessarily. The lever A and arm D may be termed a frame, which bears the cuttingtool and guides.

' Having thus described my invention, what I claim. is-

1. The combination of a lever, a spring-actuated arm pivoted thereto and arranged to projeet on the opposite side of a tree, said arm, being provided with a cutting-tool and a gage to control the depth. of cut, and the lever being provided with guides adapted to follow the groove during the operation of cutting, and thus support the machine, sulistantially as set forth.

2. A lever having a pivoted. spl-ingactuated arm arranged to project on the opposite side of the tree, said arm being provided with a cutting-tool and gage, substantially as set forth.

3. The combination of a frame bearing a cutting-tool, an adj ustable guide, and a guide adapted to yield against a spring resistance,

substantially as set forth.

4. A frame partially or entirely encompassing the tree having suitable guides to hold it in place, and provided with a cutting-tool and a gage preceding said tool having a sharpened end, substantially as set forth.

In testimony of the foregoing I have here- 10 unto subscribed my name in presence of two witnesses.

GARRETT LOW.
